Expression Pedal control of HX effects via MC6 pro

[magsterone]

I am trying to figure out how to control preset effects on my hx effects using an expression pedal on my Morningstar mc8 pro.  When selecting linear cc there is not much of an option in the midi library.  This shows also in the user manual for hx effects.  I can’t seem to grasp this concept. The hx effects allows fs control or exp control. Any guidance is greatly appreciated. Thanks

Hi,

 

Have you tried to use the Expression pedal directly connected to your HXFX. Make sure that works properly first, before introducing the Morning Star into the equation- take it one step at a time.

 

 

Hope this helps/makes sense.

1. Set up your expression pedal.
   -> https://manuals.morningstar.io/mc-midi-controller/setting-up-your-expression-pedal
2. Set up a CC Message.
   -> https://manuals.morningstar.io/mc-midi-controller/Message-Type-List.181698784.html#MessageTypeList-ControlChange
   Use CC#1 to emulate HX's EXP 1. Use MIDI channel 1 which is HX's default channel (unless you have multiple MIDI devices to control). Make sure that the channel you choose is set in HX's Global Settings.
3. On HX FX: Controller assign a parameter that you want to control with EXP 1.

If that doesn't work double check the cabling. You can connect HX FX via USB to a PC and use MIDIView to check whether HX is receiving a CC#1 message.
